I have bought a Ubisoft game on Steam, and bought its season pass product key on a retail website, which happens to be for UPlay.
It seems that I have wasted my money. That, I accept. Now, I want to buy the base game for UPlay as well because it is cheaper to buy DLC on Steam.
My question is, if I try to activate a product on UPlay, which I already own in Steam, will it say you already own the product or will it allow me to activate the base game and play the bought DLCs?
